Objectives: This study compared healthcare utilization and costs associated with switching the first-line protease inhibitor (PI) or non-nucleoside reverse transcriptase inhibitor (NNRTI) based antiretroviral (ARV) regimen due to reasons other than virologic failure among patients with HIV-1. Methods: This was a retrospective analysis of commercial and Medicare Advantage with Part D enrollees in two US administrative claims databases. The study population comprised adults with HIV-1 infection initiating antiretroviral therapy (ART) on PI- or NNRTI-containing regimens from 1 January 2006 to 31 December 2015. ⋯ Mean unadjusted non-ART costs in the switch cohort were nearly double ($2944 versus $1530, p < .001), more than double ($2562 versus $1215, p < .001) and 1.5 times higher ($1473 versus $968, p < .001) than costs in the non-switch cohort in the pre-switch, switch and post-switch periods, respectively. Conclusions: Patients with HIV-1 who initiated PI- or NNRTI-based regimens and switched ARTs for reasons other than virologic failure used more healthcare resources and incurred greater costs relative to patients in the non-switch cohort. This study highlights the importance of initiating patients on appropriate first-line ART to avoid the need to switch due to reasons other than virologic failure.

Objective: Hypoglycemia occurs in 20-60% of patients with diabetes mellitus. Identifying at-risk patients can facilitate interventions to lower risk. We sought to develop a hypoglycemia prediction model. ⋯ Non-long-acting insulin was an important risk factor. Decreased risk with age may reflect treatment or diminished awareness of hypoglycemia. More complex models did not improve prediction.

Objective: To describe pill burden before and after hepatitis C virus (HCV) treatment initiation among patients newly treated for HCV infection, and to evaluate the association between HCV pill burden and gaps in HCV therapy. Methods: This was a retrospective administrative claims study of patients treated with direct-acting antivirals (DAAs) for HCV from 1 November 2013 to 31 July 2016. HCV pill burden was defined as the pill count per day for the index HCV regimen. ⋯ The adjusted odds ratio (OR) of a ≥15-day gap in HCV therapy was 1.75 (95% confidence interval [CI] = 1.38-2.22) for patients with 2 HCV pills/day and 2.11 (95% CI = 1.78-2.51) for patients with ≥3 pills/day, compared with patients with 1 HCV pill/day. Conclusions: Patients with HCV have a substantial pill burden even before initiating HCV treatment. As higher HCV pill burden was associated with lower medication adherence, pill burden should be an important consideration in HCV treatment selection.

Background: Biologics used to treat ulcerative colitis (UC) may lose their effect over time, requiring patients to undergo dose escalation or treatment switching, and systematic literature reviews of real-world evidence on these topics are lacking. Aim: To summarize the occurrence and outcomes of dose escalation and treatment switching in UC patients in real-world evidence. Methods: Studies were searched through MEDLINE, MEDLINE IN PROCESS, Embase and Cochrane (2006-2017) as well as proceedings from three major scientific meetings. ⋯ Mean/median time to dose escalation on anti-TNF ranged from 1.84 to 11 months. The most common switching pattern, infliximab → adalimumab, occurred in 3.8% (median 5.6 years) to 25.5% (mean 3.3 years) of patients. Conclusions: Dose escalation and treatment switching of biologics may be considered as indicators of suboptimal therapy suggesting a lack of long-term remission and response under current therapies.

Objective: Some patients with interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF) develop a progressive fibrosing phenotype. We investigated the diagnosis and management of non-IPF ILDs using data from a survey of physicians and from US insurance claims. Methods: Pulmonologists, rheumatologists and internists in France, Germany, Italy, Japan, Spain, UK and US who had managed ≥10 patients with non-IPF ILDs in the past year, including those with progressive fibrosing ILDs, completed an online survey. ⋯ Conclusions: Physicians estimate that 18-32% of patients diagnosed with non-IPF ILDs develop a progressive fibrosing phenotype and that these patients experience significant delays in the diagnosis of ILD and the detection of progressive fibrosis. Between 25% and 50% of patients with progressive fibrosing ILDs do not receive drug therapy. There is an unmet need for effective and well tolerated treatments for progressive fibrosing ILDs.
